How many fasteners are required for each individual asphalt strip shingle?

• A. 3
• B. 4
• C. 6
• D. 2

Answer: (B)

Four fasteners per strip shingle are used to secure each shingle against wind uplift and weather exposure. This number provides enough holding power by distributing the load across the shingle so it stays seated as the roof moves with temperature changes and wind forces, while keeping installation practical and cost-effective. In typical residential roofing, four nails per shingle is the standard pattern; in higher wind areas or with different product specifications, more fasteners may be required, but the common practice for a standard installation is four.
